1/ Cursor users are feasting in April 2025. Five of the fastest-growing AI models just dropped—and they all slap in different ways. From OpenAI’s brainy o3 to DeepSeek’s open-source banger and Grok 3’s Elon-coded math power, here’s the breakdown on what’s hot. 👇

2/ o3 is OpenAI’s smartest model yet—multimodal, tool-powered, and can turn whiteboards into code. It crushed Codeforces with a 2,727 ELO and outreasoned everyone on ARC-AGI. It’s $0.30 per request in Cursor but flexes hard if you need top-tier agent tasks.

4/ DeepSeek V3.1 is the open-source hero of the bunch—zero cost, zero ego. It’s got great code-writing skills, supports agent mode, and competes head-to-head with the big boys. Meanwhile, GPT-4.1 quietly dominates long-context tasks (up to 1M tokens!) and beats 4.5 in coding.

5/ Then there’s Grok 3 from xAI. Designed for reasoning, math, and science—Grok’s got that problem-solver vibe. It’s agent-ready in Cursor and allegedly outperforms GPT-4 in technical tests.

6/ o3 is the big brain, DeepSeek is the free code beast, and Grok 3 is your nerdy lab partner. 🤖🧠

3/ o4-mini is the free younger sibling—smaller, faster, but still supports tools and image input. Good for most stuff without melting your credits. Pair it with Cursor’s agent mode and you’ve got a lean, mean dev assistant.
